' OF MILWAUKEE, WISCONSIN, A FIRM DRIER Application filed August 3, 1928. Serial No. 297,262.

This invention relates to a drier designed primarily for use in drying heavy fabrics such as rugs and carpets.

It has been the practice, heretofore, to suspend wet rugs after they have been cleaned and sized, in a drying room. Considerable time has been required to properly dry rugs when thus suspended because the air used for drying purposes is already moistened and because the water contained in the rug slowly drains toward the lower edges thereof with the result that the upper portions of the rugs are dried long before the lower portions thereof, any dirt that may remain in the rugs following the cleaning operation being caused to drain downwardly with this water to the bottom of the rug. Consequently the lower portion of the rug frequently retains the sediment drained from all other portions of the rug and it thus becomes practically impos sible properly to complete the cleaning and drying operation. This is a feature particularly objectionable where light rugs and fabrics are cleaned and dried.

It is an object of the present invention to provide a drying apparatus which enables a cleaned rug to be dried while flat. Consequently there is no danger of moisture draining from one part to another of the rug and depositing sediment adjacent one end. Nor is there danger of the rugs becoming distorted as a result of being suspended from one end while drying.

A further object is to utilize a drier to which hot air is supplied in suficient quantities to almost instantly absorb the moisture contained in thefabric being treated.

A further object is to provide a means for distributing the hot dry air over the surface of the entire rug or other fabric while the same is supported in a flat position whereby the said fabric will be dried flat and will be maintained in proper shape.

A still further object is to provide a drier which can be so constructed as to act simultaneously upon a plurality of rugs or fabrics.

With the foregoing and other objects in view which will appear as the description proceeds the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed without departing from the spirit of the invention.

In the accompanying drawings the preferred forms of the invention have been shown. 5

In said drawings,

Figure 1 is an end elevation of a drier embodying the present improvements, the conveyor used in connection therewith being shown in section and the air drying and heating means and the air suction means being shown more or less in diagram assembled therewith.

Figure 2 is a plan view of the drier.

Figure 3 is a section on line 3-3, Figure 2.

Figure 4 is a section on line H, Figure 3.

Figure 5 is an end elevation of the drier.

Referring tothe figures by characters of reference, 21 designates superposed heating table. The upper heating table 21 has a hood 22 extended thereover and provided, at one side, with air inlet flues 23 while the opposite side of the hoodis provided with air outlet fiues 24. The remaining walls of the hood are formed with movable closures 25. These can be hingedly mounted as shown and provided with arcuate feet 26. A foraminous conveyor 27 is mounted to travel beneath the hood and beneath the closures and is utilized for conveying a rug or other fabric into position under hood 22 and over the heating table 21 thereunder.

The space between the upper heating table 21 and the next adj oining heating table thereunder constitutes a hood 28 having air inlet flues 29 extending from one wall and air outlet fiues 30 extending from the opposite wall. These fiues 29 and 30 are extended at right angles to the fines 23 and 24. Closures 31 like the closures 25 are located in the remaining 9 walls of the hood 28 and a foraminous conveyor 32 adapted to carry a rug through this hood 28 and under the closures 31. This conveyor travels at right angles to the conveyor 27.

vided therefor. The several heating tables are adapted to be supplied with air heated to a high temperature or with steam. VVhen air is used as a plied to the flues23, 29, 34 from headers 11 heating medium it can be supveyors constituting means for carrying a flat unfolded fabric through its hood, each conveyor being movable at right angles to the next adjoining conveyor and independently thereof, means for directing heated dry air into each of the hoods, andmeans for withdrawing moisture lad'en air from each of the hoods.

In testimony that I claim the foregoing as my own, I have hereto a'flixed my signature;

HERMANN KLEIN.

in communication with an airheaterindicated generally at 12 and an air drier indicated generally at 13; This heater and drier I p 1 can be of any construction desired, it merely being essential toprovide a means whereby practically all moisture will first be removed from the air to be used in the drier after which the dry air will be heated and then supplied to the drier.

The flues 24, 30, 35 which constitute the air outlets of the drier tables are all connected through headers 14 or the like opening into any suitable mechanism, such as a suction fan 15, whereby air can be exhausted from the apparatus almost as fast as it is supplied thereto by the headers 11. As all of the heating tables are heated to a high temperature by steam or other suitable heatin medium' and as all of the hoods are furnished with a constant supply of hot dry air and with means for exhausting the air when laden with moisture, it will be apparent that a rug or other fabric conveyed into any one ofthese hoods will be quickly dried in the manner heretofore explained. By having a plurality of superposed heating tables, each with a hood,several rugs or the like can be dried simultaneously.

What is claimedis:

1. A drierincluding superposed tables, a hood extending over each of said tables," a foraminous conveyor movable through each of the hoods and supported by the table thereunder, all ofthe conveyors being movable in different directions respectively, each of said conveyors constituting means for carrying a flat unfolded fabric through its hood, means for directing heated dry air intoeach of the hoods, and means for withdrawing moisture laden air from each of the hoods.

2. A drier including superposed'heating tables, a hood extending over each of said tables, a foraminous hconveyor. movable through each of the hoods and supported by the table thereunder, one conveyor being provided for each tableand each of said'conheating,
